The woman with the long dark hair shown in the first few seconds is Amy Williams. (EDIT:First Trailer.) She won the gold medal at the 2010 Winter Olympics in Vancouver in the Skeleton event. It's a sort of one man bobsleigh for lunatics.

She is in a film clip there, so probably not an SIARPC. Maybe the TG team are throwing a Mini down a bobsleigh track?
